About Diamond Dozen Slots

Diamond Dozen, an online video slot based on the theme of diamonds, is one of the oldest, but most colorful slots in the RTG portfolio. The slot is visually appealing with bright symbols set against a dark background. The reels are heavily populated with high-value card symbols, but they suit the game well as they are studded with glittering diamonds. You cannot help, but feel wealthy as you spin the reels of this slot.

Game in Action

Diamond Dozen Slot in action

You can play this slot for fun or real money. If you need help, you can just click on the Help button at the bottom left of the reels. You will not find it difficult to adjust your bet size and the number of lines you would like to play before hitting the Spin button. If you do not like to do this manually, you can use the Autoplay option and play the slot automatically.

Although there is no ambience music, your wins will be celebrated with apt sound effects. However, to hear some lively music and view animated symbols, you will have to unlock the bonus features. The slot appears rather reluctant to spew bigger wins, but yields a number of smaller wins with each spin.


Diamond Dozen is packed with traditional slots features such as a wild symbol, a scatter symbol, and a bonus game.

The White Diamond symbol is going to be your favorite as it serves as the wild for all symbols except scatters. If you land five White Diamond symbols along an active payline, the top fixed jackpot of 3,000 coins will be yours.

The White Diamond can also do something else—unlock the Diamond Delight Bonus Feature. However, you need to get at least three White Diamonds along a payline for this. Once you have triggered this feature, you have to click on the White Diamond symbols in the combination to reveal numbers in the range of 1 - 10. These numbers are then multiplied and credited to your account as a bonus prize.

The Blue Diamond scatters can help you win up to 300 coins. All you need to do is get combinations of them on your reels. If you land at least three of them on your reels, you will win not only win scatter payouts, but also unlock the free spins round, which comprise 12 free games with doubled wins.

If you are lucky, you can also win the random progressive jackpot. Since Diamond Dozen is one of RTG’s Real Series of Slots, it features a progressive jackpot that can be won at random at the end of each paid game.

Other Slot Machines You Might Enjoy


Since it is an old RTG slot, Diamond Dozen lacks innovative slots features. It is a simple, but delightful online slot that RTG fans wouldn’t like to miss, especially as it offers generous scatter wins, a bonus game, and free spins, in which you can win much more than the top jackpot of 3,000 coins.
